I haven't attempted to reproduce the issue recently, I'm afraid. I've changed jobs twice in the intervening time, so the immediate issue for me has gone away.

[Bug 855800] Re: KVM crashes when attempting to restart migration
If you *need* to use the live migration (rather than offline migration by copying the disk images) you have already made a decision that the service is sufficiently important that you cannot have downtime on it. If the live migration could fail, and resuming it could crash (as reported), this is going to be a serious concern and most likely not a risk you would wish to take with a service that you have already decided is so vital as to not need downtime. The migration feature that if used might crash, is not a feature I would like to trust my valuable services to. Therefore I would suggest that this crash have the same priority as the migration feature. If migration is a low priority feature then it would be find as 'low' priority', but if the live migration is an important feature to have then it needs to be solid. As an administrator of services, I play have a game of Russian-roulette with them, and migration is that game at present. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/855800 Title: KVM crashes when attempting to restart migration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/855800/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Thanks for taking the time to submit this bug and helping to make Ubuntu better. Just to be sure I understand right, if you simply let the migration continue rather than canceling it, you don't get an error, right? I'll mark this low priority under that assumption. If I'm wrong, then priority should be raised.

[Bug 855800] Re: KVM crashes when attempting to restart migration
That's correct for the testing I have performed. I have been able to perform repeated migrate/migrate_cancel operations much more quickly than I have been able to perform actual migrations, therefore the test set of migrate operations after a cancel is at least an order of magnitude larger than the test set of completing migrations. Background in case it's relevant: I was doing this to test the behaviour if (for example) the target system failed during the migration and it was necessary to cancel and restart, as such resilience is important for the services I maintain.
